Application Note PDF. Contact email address: b. Menlo Systems went on tour to three national metrology institutes NMIs to demonstrate the capability of the SmartComb for laser calibration. The device was boxed up, and driven km from Munich to Vienna to Bratislava to Prague and back. A total of five metrology lasers were calibrated during the tour. The definition of the meter has been realized via Iodine-stabilized Helium-Neon lasers over the past few decades [1]. NMIs worldwide use these lasers either directly in interferometric length measurements, or they are used to calibrate other commercial and cheaper lasers, such as Zeeman-stabilized Helium-Neon lasers.

Advances in sensing, imaging, and metrology over the last decade have been critically dependent on optics and photonics, and precision sensing has moved progressively to optically based measurements. Optical techniques are already at the core of some of the most precise measurements. Precision metrology is important for advances in the following: fundamental research that relies on precision measurements, communication that relies on precision timing for high data rates and long ranges, and the Global Positioning System GPS , which relies on precision timing. GPS devices were just becoming commercially available in , and now they are in nearly every cell phone.

Why Laser instruments used? Laser Instruments are devices to produce powerful, monochromatic collimated beam of light in which the waves are coherent. Photon comes in contact with another atom or. The sequence of triggered identical photon from stimulated atom is known as stimulated emission. Time taken to travel one wavelength is called time period T. Maximum disturbance of wave is called amplitude A.
